Combining QML to Qt Application

[Veera]

Hello!!

I am running a Qt Application in Visual Studio and I would like to combine my QML code into the Qt Application.

I have added qml file in the resources folder of the Qt application and tried to combine it with the following code:


QQuickView *view = new QQuickView();
view->setSource(QUrl("main.qml"));

When I use this code I get 24 unexpected external symbol errors. I would really appreciate the help!

Thank you!

What are the errors? What do you have assigned to QT variable in your pro file?

I am using Visual Studio with Qt and I think I need not add anything to .pro file.

And what exactly are you trying to do?

Great. What do you need from us then?

I would like to use the Image in QML as a toolbox in the Qt project. I am using Qt with visual studio and I will be glad if someone could help me with the code.

Linking problems would indicate the code itself is okay. However since you are trying to combine the widget and QtQuick worlds, you surely need to derive your application from QApplication and not QGuiApplication. And for that you need to link against the widgets module.
